PURPOSE:To make uniform the thickness of each constituting element such as characters, by extending the pulse of character signal by 10-100% of the length toward the main scanning of the minimum element of the dot pattern and scanning and recording the laser light with extended pulse. CONSTITUTION:The character signal read out from the magnetic tape unit 4 enters the character generator 9 and outputs the parallel dot signal S4 via the control signal S3 of the timing control circuit 8. the signal S4 enters the parallel-serial conversion circuit 10 and is converted into the signal S6 with the control signal S5 from the timing control circuit 8. The signal S6 feeds the signal S7 delayed at the delay circuit 11 to the OR circuit 12, the logical sum of S6 and S7 is taken, and the signal S8 extended with the pulse length is output. Ths signal scans the laser light and recording is made on the heat mode recording material, allowing to make uniform the thickness of each recording element such as characters. |
